The TI Programmer was a real unusual calculator, because it can calculate also with hexadecimal and octal numbers, means not only add and substract, but also bit operations like AND, OR, XOR or SHIFT. This was one of the earliest devices of it's kind, although it was not the first (the SR-22 was the first). But it's still worth to be presented, also because not many was sold since it's debut in 1977. Technically it's very similar to the TI-30.

It's funny to look what the calculator does after a bit idle time. Something is running through the display ...

(it was too much work to animate all 8 possible dots, but all 8 positions are used)
